The slope of the graph of plane A is 430, its speed is 430 miles per hour.

The slope of the graph of plane B is 460, its speed is 460 miles per hour.

Plane B is flying faster.

Step-by-step explanation:

The speed of the airplane is the slope of the function, that is, change in distance by change in time. From table, we notice that curve is a first order polynomial, also known that linear function:

Plane A

The slope of the graph of plane A is 430, its speed is 430 miles per hour.

Plane B

The slope of the graph of plane B is:

\(v = \frac{1840\,mi-460\,mi}{4\,h-1\,h}\)

\(v = 460\,\frac{mi}{h}\)

The slope of the graph of plane B is 460, its speed is 460 miles per hour.

Therefore, plane B is flying faster.

The joint probability of x and y, given y=y and x follows an exponential distribution with parameter y, is:

P(x=x, y=y) = e^(-x-y) / y

To find the joint probability of x and y, we can use the conditional probability formula:
P(x=x, y=y) = P(x=x | y=y) * P(y=y)

Since we know that y follows an exponential distribution with parameter 1, we can write:
P(y=y) = f(y) = e^(-y)

Now, to find the conditional probability of x given y, we can use the probability density function of the exponential distribution:
f(x | y=y) = λ * e^(-λ*x)

where λ = 1/y, since y is the parameter of the exponential distribution.

Therefore,
P(x=x | y=y) = (1/y) * e^(-x/y)

Combining these equations, we get:
P(x=x, y=y) = (1/y) * e^(-x/y) * e^(-y)

Simplifying this expression, we get:
P(x=x, y=y) = e^(-x-y) / y

So the joint probability of x and y, given y=y and x follows an exponential distribution with parameter y, is:

P(x=x, y=y) = e^(-x-y) / y

The exact values of the expressions without solving for x is

sin(2x) = √15/8

cos(2x) = 7/8

tan(2x) = 2√15.

Given that sin(x) = 1/4 and x is in quadrant I, we can use the given information to find the exact values of the expressions without explicitly solving for x.

(a) To find sin(2x), we can use the double-angle identity for sine:

sin(2x) = 2sin(x)cos(x)

Using the value of sin(x) = 1/4, we have:

sin(2x) = 2(1/4)cos(x)

Since x is in quadrant I, both sin(x) and cos(x) are positive. Therefore, cos(x) is equal to the positive square root of (1 - sin^2(x)).

cos(x) = √(1 - (1/4)^2) = √(1 - 1/16) = √(15/16) = √15/4

Substituting the values, we get:

sin(2x) = 2(1/4)(√15/4) = √15/8

Therefore, sin(2x) = √15/8.

(b) To find cos(2x), we can use the double-angle identity for cosine:

cos(2x) = cos^2(x) - sin^2(x)

Using the values of sin(x) = 1/4 and cos(x) = √15/4, we have:

cos(2x) = (√15/4)^2 - (1/4)^2 = 15/16 - 1/16 = 14/16 = 7/8

Therefore, cos(2x) = 7/8.

(c) To find tan(2x), we can use the identity:

tan(2x) = (2tan(x))/(1 - tan^2(x))

Using the value of sin(x) = 1/4 and cos(x) = √15/4, we have:

tan(x) = sin(x)/cos(x) = (1/4)/(√15/4) = 1/√15

Substituting the value of tan(x) into the formula for tan(2x), we get:

tan(2x) = (2(1/√15))/(1 - (1/√15)^2) = (2/√15)/(1 - 1/15) = (2/√15)/(14/15) = 30/√15

To simplify further, we rationalize the denominator:

tan(2x) = (30/√15) * (√15/√15) = (30√15)/15 = 2√15

Therefore, tan(2x) = 2√15.

When gathering data, using two or more methods to confirm results is called option (c) triangulation

Triangulation involves using multiple methods or sources to collect data in order to validate or confirm results. By using different methods, researchers can obtain a more complete and accurate understanding of the phenomenon being studied, reducing the risk of bias or error. For example, a researcher might use both surveys and interviews to gather information about a particular group of people.

This approach can help to ensure that the data collected is reliable and can be used with confidence to draw conclusions. Triangulation is widely used in social science research, but can also be applied in other fields where multiple sources of information are available.

Answer:

No they are not equivalent

Answer:

C

Step-by-step explanation:

3x - 9y = 9 → (1)

- 2x +2y = 8 ( subtract 2y from both sides )

- 2x = - 2y + 8 ( divide through by - 2 )

x = y - 4

substitute x = y - 4 into (1)

3(y - 4) - 9y = 9

3y - 12 - 9y = 9

- 6y - 12 = 9 ( add 12 to both sides )

- 6y = 21 ( divide both sides by - 6 )

y = \(\frac{21}{-6}\) = - \(\frac{7}{2}\)

Given the total number of notes is eight and their value total is $550, then you have 5 notes of $50 and 3 notes of $100

As per the question statement, You have \(x\) number of $50 notes and \(y\) number of $100 notes. Their total value of $550 and total number of notes are eight. We are supposed to calculate the value of \(x\) & \(y\)

This question is a classic example of how to form and solve linear equations. For solving this, we will have two equations, both in two variable x and y.

As we have total 8 notes, therefore,

\(x+y=8\)

And their total value is 550, therefore,

\(x*50+y*100=550\)

From 1st equation we get, \(y=8-x\)

substituting this in another equation, we get

\(x*50+(8-x)(100)=550\\50x+800-100x=550\\800-50x=550\\50x=250\\x=5\)

Solving for y, we get

\(y=8-x\\x=5\\y=8-5\\y=3\)

Therefore we have 5 notes of $50 i.e., \(x=5\) and 3 notes of $100 i.e., \(y=3\)

Explanation: W stands for weight. So the weight must be under 1,800 pounds. And B clearly shows the answer because the smaller side is facing how much weight you have on the elevator and the smaller side of math symbol means how much weight you have on the elevator is less than 1,800 pounds.

( ">" has a line under it)

Answer:

Step-by-step explanation:

Perimeter 165 cm

1st.   65 cm < 2s

3rd.  10 cm < s

The 2nd side is twice than the first side but 10cm longer than the

3rd side, so it'll be

2nd.   2s + 10

a triangle has a perimeter of 165 cm. the first side is 65cm less than twice the second side. the third side is 10cm less than the second side. write and solve an equation to find the length of each side of the triangle

FIRST, we need variables. Once we define variables, it's much easier to turn this word problem into a math problem.

Let a = first side

Let b = second side

Let c = third side

NOW, we can turn the words into equations:

"a triangle has a perimeter of 165 cm."

a + b + c = 165

"the first side is 65cm less than twice the second side."

a = 2b - 65

"the third side is 10cm less than the second side."

c = b - 10

Before we finish, I have to ask: Who writes problems like this??? Pointless problems like these are why kids don't like math! Ugh. Drives me crazy. It's a shame, because solving math problems really does have a certain satisfaction, once you learn how. [Okay. I'm done. Back to the problem.]

If we could get this to have only one variable, we could solve it. Substitution to the rescue!

a + b + c = 165 (rewrote equation from above)

(2b - 65) + b + (b - 10) = 165 (substituted "a" and "c" from equations above)

See how that works? Let's solve it.

2b - 65 + b + b - 10 = 165 (dropped the parentheses, because there was nothing to distribute, not even a minus sign)

4b - 75 = 165 (combined like terms)

4b = 240 (added 75 to both sides)

b = 60 (divided both sides by 4)

We found the second side! We can find the first and third sides using those equations from above:

a = 2b - 65

a = 2*60 - 65

a = 120 - 65

a = 55

c = b - 10

c = 60 - 10

c = 50

All done.

The marginal profit function is p'(x) = -0.02x + 7. the marginal profit function is the derivative of the profit function with respect to the quantity x.

in this case, the profit function can be calculated by subtracting the cost function (c(x)) from the revenue function (r(x)).

given:

c(x) = 281 + 0.2x (cost function)

r(x) = 8x - 0.01x² (revenue function

the profit function p(x) is given by:

p(x) = r(x) - c(x)

substituting the given values:

p(x) = (8x - 0.01x²) - (281 + 0.2x)

simplifying the expression:

p(x) = 8x - 0.01x² - 281 - 0.2x

p(x) = -0.01x² + 7.8x - 281

to find the marginal profit function, we take the derivative of the profit function with respect to x:

p'(x) = d/dx (-0.01x² + 7.8x - 281)

p'(x) = -0.02x + 7.8 8.

=====================================================

Explanation:

The given graph passes through (0,2) and (2,5)

The slope of this line is

m = (y2 - y1)/(x2 - x1)

m = (5-2)/(2-0)

m = 3/2

Since the y intercept is b = 2, we go from y = mx+b to y = (3/2)x+2, which is the equation of the graphed line shown.

Any parallel line will have the same slope, but a different y intercept.

-------------------

The parallel line must pass through (x,y) = (3,2). We'll use these coordinates along with m = 3/2 to find the y intercept b

y = mx+b

2 = (3/2)(3)+b

2 = 9/2+b

2-9/2 = b

4/2 - 9/2 = b

-5/2 = b

b = -5/2 ... is the new y intercept

The equation of the parallel line is y = (3/2)x-5/2, which is in slope intercept form

-------------------

Let's convert to standard form

y = (3/2)x-5/2

2y = 3x-5 .... multiply everything by the LCD 2 to clear out fractions

2y+5 = 3x

3x = 2y+5

3x-2y = 5 ... is the equation in standard form of the parallel line

-------------------

As a check, we can plug (x,y) = (3,2) into that last equation above to get

3x-2y = 5

3*3-2*2 = 5 ... replace x with 3, replace y with 2

9-4 = 5

5 = 5

Confirming that (x,y) = (3,2) is on the line.
